W25Q16JV 16Mbit SPI Flash

@@ -0,0 +1,58 @@+# W25Q16JV++**Winbond** · SPI NOR Flash · SOIC-8 (208 mil)++The W25Q16JV is a 16 Mbit (2 MB) serial NOR flash memory. It supports Standard, Dual, and Quad SPI at clock rates up to 133 MHz, organizing its array into 256-byte pages, 4 KB sectors, and 32/64 KB blocks. It is a common choice for MCU firmware storage, code shadowing, and data logging.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | /CS | input | Chip Select input (active low). When /CS is high the device is deselected and DO/IOx are high-impedance; when brought low the device is selected and instructions can be issued. A pull-up resistor on /CS is recommended to hold it high during power-up. |+| 2 | DO/IO1 | bidirectional | Serial Data Output (Standard SPI); becomes bidirectional IO1 in Dual/Quad SPI mode. Data is shifted out on the falling edge of CLK. |+| 3 | IO2 | bidirectional | Data Input/Output 2, used only for Quad SPI instructions. In Standard/Dual SPI mode this pin may be used as /WP (write protect) depending on QE status register bit. |+| 4 | GND | power_in | Ground reference (0V) for the device. |+| 5 | DI/IO0 | bidirectional | Serial Data Input (Standard SPI); becomes bidirectional IO0 in Dual/Quad SPI mode. Instructions, addresses and data are shifted in on the rising edge of CLK. |+| 6 | CLK | input | SPI Serial Clock Input. Provides the timing reference for all serial input/output operations. Supports up to 133MHz. |+| 7 | IO3 | bidirectional | Data Input/Output 3, used only for Quad SPI instructions. In Standard/Dual SPI mode this pin may be used as /HOLD or /RESET depending on the QE status register bit. |+| 8 | VCC | power_in | Power supply, 2.7V to 3.6V. Recommended decoupling: 100nF ceramic close to the pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Density | 16 Mbit (2 MB) |+| Interface | SPI: Standard / Dual / Quad |+| Max clock | 133 MHz (Quad up to 532 MHz equivalent) |+| Page size | 256 bytes |+| Sector / block | 4 KB sector, 32 KB / 64 KB block |+| Supply voltage | 2.7 V to 3.6 V |+| Endurance | 100,000 erase/program cycles |+| Operating temperature | -40 C to 85 C |++## Ordering variants++- `W25Q16JVSNIQ`+- `W25Q16JVSSIQ`+- `W25Q16JVSTIQ`+- `W25Q16JVUXIQ`+- `W25Q16JVZPIQ`+- `W25Q16JVUUIQ`+- `W25Q16JVXGIQ`+- `W25Q16JVBYIQ`++## CAD (KiCad official)++- Symbol: `w25q16.kicad_sym`+- Footprint: `w25q16.kicad_mod`+- 3D model: SOIC-8 208 mil (wide) body from KiCad `Package_SO/SOIC-8_5.3x5.3mm_P1.27mm`.++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Winbond datasheet](https://www.winbond.com/resource-files/w25q16jv%20spi%20revd%2008122016.pdf) (74 pp, sha256 `97430b7ae9fc3758`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
